To @ZZ whom it may con/cern,.-

Be it known that we, CHARLES ELoox WOOD, a resident of the borough of Manhat?l I States, have invented certain new and useful Improvements in Primary Batteries, of

.which the following is a s ecification In primary batteries eretofore made as known to us usin cupric oxid as contained in a\ erfor-ated cy inder it has been customary or the recharges Ato be supplied in cans, which necessitates the removal of the perforated cylinder from the jar, removal of the refuse oxid, recharging the cylinder with l oxid, and replacing the parts, the cans containing the recharges being thrown away.

The object of this invention is to rovide means to permit cupricoxid or other epolarizer to be packed for trans ortation in perforated retainers that are to e used in the batteries in such manner that the oxid 'will be prevented from sifting through the perforations of the retainer during transportation and handling, whereby perforated retainers or cylinders ina be charged with the oxid,

shipped to destination, and adjusted in the battery-jars without the necessity of handlingthe oxid in any manner, the used or exhausted retainer being discarded or thrown.

away. To this end we rovide a binder for retaining the cupric oxid within the perforated retainer or cylinder, which binder is soluble inthe liquid or solution of the battery,

.and such binder is either mixed with the cupric oxid or the perforationsin the cylinder are filled with or covered by such binder.

The invention comprises the novel details of improvement that will be more fully hereu inafter set forth and then pointed out in the claims.A e

Reference is to be had to the accompanyin drawings, forming art hereof, whereinl igure 1 is a vertica section of a primary battery embodying our` invention substantially on the line 1 1 in Fig. 2. Fig. 2 is an enlarged detail section through the perforated retainer, showing the binder applied to the Walls of the retainer. y

n Similar numerals of'reference indicate corresponding parts in the several views.

The numeral 1 indicates the jar 2, its cover; 3, the zinc, and 4 the binding-post connecting with the oxid retainer' or cylinder, which may be of usual construction. In the drawings the retainer or holder Jfor the cupric oxid is shown in the form' of two perforated shells or cylinders 5 6, one within the other in the space 7, between which cylinders the cupric oxid 8 is located, the ends of such. space being closed by covers 9 10, to which the cylinders 5 6 are attached. The rod 11 is shown connecting the cover 9 with the bindingfpost 4, whereby the retainer is supported from the cover 2. The cupric oxid in granular or analogous form is charged into the space 7 and is mixed with a binder, caus ing the particles to adhere together to prevent them frompassing through the apertures in the cylinders 5 6, which-binderis soluble f in the liquid or solution used in the cell. We may use sugar or similar saccharine matter, which is mixed with lthe oxid in such proportionas will assure the adherence together of the` particles, or, as shown in Fig. 2, the binder or sugar is filled in the apertures in the cylinders 5 6 or is pasted along the wall thereof, either inside or outside, or both, so as to prevent the loose cupric oxid that is charged in the space 7 from passing through the a ertures, such binder being soluble in the so ution or the liquid of the cell, as before explained. These retainers charged with the cupric oxid or depolarizer provided with the binder preventing the oxid from passing through the apertures of the retainer are to be furnished ready for use, so that when a cell or battery is to be recharged. with the oxid it is merely' necessary to remove the Old and used-up retainer, which may be discarded and apply a new retainer by passing the rod 11 through it and attaching it to the binding-post 4. These perforated retainers may thus be charged at' the factory and shipped without danger that y the oxid will be lost therefrom, and thereby the re uirement of removing used-up or exhauste oxid from a retainer and recharging the latter from a can or the like is overcome', thereby enabling the quicker recharging Vof the cell or battery and saving the annoyance and inconvenience incident to recharging retainers in the ordinary manner. The zinc 3 rests upon insulating-blocks 13, held u on the retainer by a band or ring 12, adapte to rio l other Welldmown corresponding materiel for the urpose of depoleriziug may-be used aeeor ing to the character of the battery.

Havmg 110W described our invention,'what 5 We claim isv v 1. A battery element comprising a perforated retainer containing a depolarizer and having a binder soluble in4 e. battery liquid or solution for preventing such depolarizer from ro/passing through-th'perforatione'in the re `tainer,'substaritia.1ly as described'.

2. A' battery element comprising perforated shells disposed one Within mother pro- Viding a space closed at opposite ends, e depolarizer Within said space, and e binder soluble in e. battery liquid or solution serving to prevent the depolarizer 'from passing through the perforations of the shells, substantially' as described.
